I-Sintered SiC Ceramics: Izinzuzo ze-SiC Ceramic Ballistic Products
Imikhiqizo ye-silicon carbide ceramic engangenisi izinhlamvuziya ngokuya zithandwa kakhulu emkhakheni wokuvikelwa komuntu siqu kanye nezempi ngenxa yokusebenza kwazo okuhle kakhulu kanye nokusebenza kwazo. Lezi zitsha zobumba zinokuqukethwe kwe-SiC okungu-≥99% kanye nobunzima (HV0.5) okungu-≥2600, okwenza zibe yizinto ezikhethwayo zokusetshenziswa kwe-ballistic njengezigqoko ezingangeni zinhlamvu kanye nezimpahla zokuvikela zamathangi nezimoto ezihlomile.
Umkhiqizo oyinhloko walolu chungechunge yi-silicon carbide ceramic bulletproof sheet. Ubuningi bayo obuphansi kanye nesisindo sayo esincane kwenza ifaneleke kakhulu imishini yamasosha engangenisi zinhlamvu, ikakhulukazi njengolwelwesi lwangaphakathi lwamavesti angangenisi zinhlamvu. Ngaphezu kwalokho, inikeza izinzuzo ezibalulekile maqondana nokuqina, amandla kanye nokuzinza kokushisa.
I-Silicon carbide (SiC) ceramics inezakhiwo ezimbili zekristalu, i-cubic β-SiC kanye ne-hexagonal α-SiC. Lezi ceramics zinezibopho eziqinile ze-covalent, izakhiwo ezingcono zemishini, ukumelana ne-oxidation, ukumelana nokuguguleka kanye ne-coefficient ephansi yokungqubuzana kunezinye i-ceramics ezifana ne-alumina ne-boron carbide. Ukuqhuba kwazo okuphezulu kokushisa, i-coefficient encane yokwanda kokushisa, kanye nokumelana okuhle kakhulu nokushaqeka kokushisa kanye nokugqwala kwamakhemikhali kwenza kube lula kakhulu ukusetshenziswa kwazo okubanzi.
Isimiso sokuvikela izibhamu se-silicon carbide ceramics sisekukwazini kwaso ukuhlakaza nokumunca amandla ezibhamu. Nakuba izinto zobunjiniyela zendabuko zimunca amandla ngokuguqulwa kwepulasitiki, izinto zobumba, okuhlanganisa ne-silicon carbide, zenza kanjalo ngama-microfractures.
Inqubo yokumunca amandla e-silicon carbide bulletproof ceramics ingahlukaniswa ngezigaba ezintathu. Ngesikhathi sokuqala kokushayisana, inhlamvu ishaya indawo ye-ceramic, ithuntuthe inhlamvu futhi ichoboze indawo ye-ceramic, idale izindawo ezincane neziqinile eziqhekekile. Ngesikhathi sesigaba sokuguguleka, inhlamvu engabonakali iyaqhubeka nokuguguleka indawo yemfucumfucu, yakha ungqimba oluqhubekayo lwemfucumfucu ye-ceramic. Ekugcineni, ngesikhathi sokuguguleka, ukuqhekeka kanye nezigaba zokuqhekeka, i-ceramic ibhekana nokucindezeleka kokudonsa, okuholela ekuqhekekeni kwayo ekugcineni. Amandla asele abese ehlakazeka ngokuguqulwa kwezinto ze-backplate.
Lezi zakhiwo ezinhle kakhulu kanye nenqubo yokumunca amandla enezigaba ezintathu ivumela imikhiqizo ye-silicon carbide ceramic ballistic ukuthi inciphise ngempumelelo umthelela wezinhlamvu futhi izenze zingabi nangozi. Isilinganiso sokumelana nezinhlamvu sifinyelela ezingeni elijwayelekile laseMelika 4, elihlinzeka ngokuvikelwa okuphezulu futhi liyisinqumo sokuqala sochwepheshe bezempi emhlabeni.
Ngamafuphi, i-sintered silicon carbide ceramic ceramic ceramic ceramic ceramic chungechunge lwemikhiqizo ye-bulletproof inezinzuzo ezihlukile ngokwezakhiwo zemishini, ukuzinza kokushisa, kanye nokusebenza kahle kwe-bulletproof. Ngezakhiwo zazo eziphakeme, lezi zi-ceramic zisetshenziswa kabanzi njengezinto zokubopha amavesti angenazo izinhlamvu kanye namadivayisi okuvikela amathangi nezimoto ezihlomile. Ubuningi bazo obuphansi kanye nesisindo esincane kuzenza zilungele ukuvikelwa komuntu siqu kwe-ballistic. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, singalindela intuthuko eyengeziwe kanye nokusetshenziswa kwalezi zi-ceramic ezimangalisayo ekuvikelweni komuntu siqu nakwezempi.
